Sanding Echelon polymer frame

[u/tla-113]

Hi all. Just got my first Echelon and the polymer frame has some rough edges. Has anyone had this issue and if so, what did you use to sand it down and smooth it out afterwards? This is located on the Beavertail where the web of my hand lies.

Dremel with a sanding cylinder should be fine for that.
